Performance evaluation of H2O-LiBr absorber operating with microporous membrane technology
Vega Blázquez, Mercedes de; Venegas Bernal, María del Carmen; García Hernando, Néstor; Ruiz-Rivas, Ulpiano
With the aim of reducing the size and increasing the energy efficiency of absorption chillers, the use of microporous membrane technology in these systems is at present under study. In particular, the simulation of a H2O-BrLi absorber using porous fibers for the heat and mass transfer between the solution and the vapor phase is considered in the present work. Heat and mass transfer process are modeled by means of selected correlations and data gathered from the open literature. Using the model developed, a simulation of the absorber is performed using typical operating conditions of absorption cooling chillers.

Design of a statistical strategy to the control of a fluidized bed equipped with a rotating distributor
Gómez Hernández, Jesús; Soria Verdugo, Antonio; Villa-Briongos, Javier; Santana Santana, Domingo José
The present work proposes the use of the so-called "moving mean control charts" for the continuous monitoring of the fluidized bed. A rotating distributor was used as a counteracting measurement against the defluidization phenomena. The results showed the utility of the proposed strategy to identify the defluidization and recuperation processes.

Analysis of biomass and sewage sludge devolatilization using the distributed activation energy model
Soria-Verdugo, Antonio; García-Hernando, Néstor; García-Gutiérrez, L.M.; Ruiz-Rivas, Ulpiano
The thermal decomposition of biomass (pine pellets) and sewage sludge was studied using thermogravimetric analysis under an inert atmosphere and the Distributed Activation Energy Model (DAEM) was employed. The activation energy and the frequency factor that characterize the kinetics were determined for both samples. A simplification of the process for prediction of devolatilization curves was proposed, evaluating its validity for both cases. The simplified method was found to combine both simplicity and low deviations with experimental data.
